Quantifying response of soil methane production potential to temperature change in different wetland vegetation are vital to accurately evaluate effect of climate change on wetland ecosystem carbon balance. Soil samples at a depth of 0~30cm (5cm interval) from three typical tidal marsh ecosystems dominated by Cyperus malaccensis,Phragmites australis and Spartina alterniflora, respectively, in the Min River estuary were collected in February 2012,and soil methane production potentials were determined using anaerobic incubation method. The results showed that there is an exponential correlation between methane production potential and soil temperature. The averaged Q_(10) value of three marsh vegetation zones were 5.04, 14.92, 14.81, and 3.56, 4.99, 3.43, respectively, with temperature rasing from 10 to 20℃ and from 20 to 30℃. Vegetation type, incubation temperature and soil depth had significant effects on the methane production potential and Q_(10) value (P<0.05).
